A t pa sing through the armature .18 and L 4. However, the inalxeacd the armature i has a 1" action than the make-an: the armature 18, anal a consequence the armature 18 vibrates so quickly that the Iflllifi illVl-blffiflk device 15, it; of the armature 7 does not have time to operate, but in-' stead forms a closed circui l Vlien the armature 7 operated through the push Toutton 28, the armature l8 drawn toward the magnet butas there s no current in this 1oalre-aml-incalr device itsaction is practically nil.

u. relation to t sucl: striker deflected ugiwardly sl it/l3], as shown m i 4/. The armature 18 in this instance acts as a buzzer, ancl does not have any strikic elem nt connected thereto. rom the foregoing it will be seen that tlzcre l been p ovialetl in one unitary mature three (iismnet sicaalc which utilize be ween them only two coils. The arrangen ()3. the armature-s about the coils is novel, and provi leo c compact structure per-- muting; the employment of bells, one superposed over the other, together with a hnzczer between time cell armatnres. The circuit For energizing those coils novel, but it will. be umiel coil that invention is not limited to this circuit, and that the arn'iaturos may be operated. in any other suitable manner.

hat l claim as my invention and desire to secure by Letters Patent is l. A signal comprising a base, a stanclarfl from said base, two bolls supported in spaced relation on said standard one above the other, two strikers-one for each bell, and electromagnetic means on the base tor operating either or" said strikers.

A signal comprising a base, a standard ri 11g from the base, two bells of different dianuotcrs mounted in spaced. relation ontlie standard, the one of smaller diameter extending partially within the one of larger diameter, and two strikers operating on opposite skies of the bells, one cooperating with the smaller bell and the other co'o'pcrating with the larger bell.

A signal comprising a base, a standard rising from the base, two bells of clifierent diameters mounted in spaced relation on the stands an electromagnet having coils ared in parallel. relation on the base and extending toward the bells, twoarmatures pivotally mounted on opposite sides of the elcctromagnet in proximity to the ends of the coils most remote from the bells, and strike carried by the swinging ends of the armatu res 4-. In a; signal, two parallel and inclepen-' clently controllable coils having a common pole piece at one end and separate pole pieces the other end, and two armatures, one pivotcii. in proximity to the common pole piece anrl having its free end adapted to cooperate with one the separate pole pieces, and tire other a'rn'iature cooperating with the two separate pole pieces In a signal, two parallel and independently controllaialc coils having a common 10o pole piece at one end ancl separate pole pieces at the other encl, the separate pole pieces lacing extended to the outer sides of the coils, aw two arn'iatures pivotally' mounted. in proximity to the common pole piece and having their free curls adapted to cooperate with the separate pole pieces. I

8. In an clectromagnet, two armatures cooperating tl'lercwitii, two make-antlbreak devices controlled by the armatures, one of said malre-ancl-brcak devices being an ranged in the circuit of the other make-andlorealr device and having a smaller frequency of action than such other device so that it (lees not operate when such other make-anclbreak device is operating.

7. In a signal, anelectromagnet, two armatures cooperating therewith, two 1'll21k6fl11dbreak clevices, and two circuits one of which includes the leetromagnet, one armature and one makeami-lircak device, While the other includes tlic'elcctrornagnct, both armatures and both make-anrl-break devices, the makeencl-brealr device which is included alone in the first circuit having a smaller frequency of action than the other make-andbrealc device, so that the first make-unclbreak device remains inactive during the action of the second makc-and-brcak device.

f, In a signal, a single electromagnet l1aving two zu'znatures, two make-and-break devices one of which has a smaller frequency of action then the other, and two circuits one of which includes the electromagnet and both mak -and-break devices and. ehe ether of which includes the electromagnet and only one of the make-and-breek devices.

9. In a signal, an eleeiro eegnet having a izwo ermatures arranged. on opposite sides' of said. pair, a third armature arianged at one end of the pan, and means the vibration-0% any we of the armature-s without efiectip the vibration of other one of the armetures.
